Hello
The issue was solved, it seems that it was related to setup which doesn’t suits to the drivers and DT requirements, to make the drivers write registers successfully, in port A of the deser, it has to be a serializer with 0x40 and in port b a serializer with an addr 0x62. Or both of the serializers of the camera must have 0x62 as serializer address.
Setup 1 (Not working)
LI VENUS IMX623 GMSL2 → In Deser MAX9296 Port A
LI AR0820 GMSL2 → In Deser MAX9296 Port B
Setup 2 (Working)
LI VENUS IMX623 GMSL2 → In Deser MAX9296 Port A
GMSL2 Camera with a MAX9295B ser with i2c addr 0x62 → In Deser MAX9296 Port B
Setup 3 (Working)
GMSL2 Camera with a MAX9295A ser with i2c addr 0x40 → In Deser MAX9296 Port B
LI VENUS IMX623 GMSL2 → In Deser MAX9296 Port B
You have also to unplug and plug again the power supply of the deserializer if the cameras were not initialized correctly before rebooting
